Recreate the barplot below that shows the population of different continents for the year 2007.
Hints:
# YOUR CODE HERE
df_2007 = df.query('year==2007')
df_2007_new = df_2007.groupby('continent').sum()
fig = px.bar(df_2007_new, x="pop", orientation='h', color = df_2007_new.index)
fig.show()
df_2007_new.head()
fig = px.bar(df_2007_new, x="pop", orientation='h', color = df_2007_new.index)
fig.update_layout(barmode='stack', yaxis={'categoryorder':'total ascending'})
fig.show()
Add text to each bar that represents the population
# YOUR CODE HERE
fig = px.bar(df_2007_new, x="pop", orientation='h', color = df_2007_new.index, text_auto='.2s')
fig.update_layout(barmode='stack', yaxis={'categoryorder':'total ascending'})
fig.show()
Thus far we looked at data from one year (2007). Lets create an animation to see the population growth of the continents through the years
# YOUR CODE HERE
fig = px.bar(df, x="pop", y='continent', orientation = 'h', hover_name = 'country', animation_frame="year",
color = 'continent', range_x=[0,4000000000])
fig.update_layout(barmode='stack', yaxis={'categoryorder':'total ascending'})
fig.update_traces(marker_line_width=0)
fig.show()
Instead of the continents, lets look at individual countries. Create an animation that shows the population growth of the countries through the years
# YOUR CODE HERE
fig = px.bar(df, x="pop", y='country', orientation = 'h', animation_frame="year",
color = 'continent', range_x=[0,1500000000])
fig.update_layout(barmode='stack', yaxis={'categoryorder':'total ascending'})
fig.update_traces(marker_line_width=0)
fig.show()
Clean up the country animation. Set the height size of the figure to 1000 to have a better view of the animation
# YOUR CODE HERE
fig = px.bar(df, x="pop", y='country', orientation = 'h', animation_frame="year",
color = 'continent', range_x=[0,1500000000], height = 1000)
fig.update_layout(barmode='stack', yaxis={'categoryorder':'total ascending'})
fig.update_traces(marker_line_width=0)
fig.show()
# YOUR CODE HERE
fig = px.bar(df, x="pop", y='country', orientation = 'h', animation_frame="year",
color = 'continent', range_x=[0,1500000000], range_y = [132, 142], height = 500)
fig.update_layout(barmode='stack', yaxis={'categoryorder':'total ascending'})
fig.update_traces(marker_line_width=0)
fig.show()
